'Ihey tive can beviewed so as'to exhibit in colors the 45 might be placed between thesensitive lm and stereoscopic or changeable eilect obtained withthelined screen. They might form a part of the out colors in my olderinventions. I will begin design of the lined screen itself, in whichcaseit with the case of a positive on glass or other might have such anappearance as is shown in transparent material, which is to be viewed byfront elevation on an enlarged scale in Fig. 1, in transmitted light.One of the several possible 50 which the areas 1 are opaque, the areas2' are arrangements is shown in Fig. 2, which may be yellow, the areas 3are blue and the areas 4 are compared with Fig. 6 of my. Patent No.1,260,682, red. 'Ihey might be placed between the support whichillustrates a similar device for exhibiting of the screen lm and thevscreen film. They stereoscopic or changeable transparencies but 55 mightconsist of colored areas in the support vWithout colors. It diers fromFig. 6 in pre- 65 senting at a transparent support carrying on its rearface and adjacent to the photographic lm at 6 a color screen 7,consisting of alternating horizontal colored lines or other patternshaving the same form as the distributions of color on the photographicplate when it was exposed and so disposed relative to the positive film6 that each area of this positive lm has superimposed upon it an element`of color screen of substantially the same color as the light that fellupon the corresponding part of the photographic plate when it wasexposed in the camera.

The support 5 might be omitted, the color screen 7 being in the form ofcolored lines or patterns printed or otherwise applied directly upon thephotographic film 6.v In that case the film 6 with the color screen 7would still need to be separated by a space of suitable thickness fromthe lined screen 8. The support 5, instead of entirely lling this space,might fill it only partially. Another variation of the 'arrangement ispresented by placing the color screen 7 immediately behind thephotographic illm 6, instead of immediately in front of it as in Fig. 2.In this case again the iilm 6 and the color screen 'I may be bothIcarried by the same support or each.

carried by a separate support.

A method of exhibiting opaque stereoscopic or changeable pictures incolors using reflected light is shown in Fig. 3. This may be comparedwith Fig. 1 of my Patent No. 1,150,374, which presents a method ofexhibiting such pictures without colors. 'Ihis device diil'ers from thatof said Fig. 1, in that in front of the positive photographic film 9,there is placed a color screen 10, which presents the same distributionof color as the distribution 'of colors on the photographic plateexposed in the camera. In place of this arrangement the color screenmight be placed 'directly behind the photographic film 9, instead ofdirectly in front of it. The photographic illm 9 is carried upon al base11, while the color screen 10 has a sheet of transparent material 12disposed in front of it having magnifying ridges formed in the facethereoi'.

In the preceding paragraphs I have referred especially to color screenscomprising colors disposed in alternating horizontal lines. While Iprefer this pattern, there are many other patterns in which the colorsmight be distributed and I do not limit myself to this pattern. However,it is not desirable that the colors should be disposed in. verticallines, or lines that are nearly vertical, because then there might beopposite one of the verticaltransparent lines 4of the lined screen, oropposite a considerable portion of the line only a single color, andthen a true reproduction of the clors of the object photographed couldnot in general be accomplished.

By the term lined screen in the claims, I contemplate any arrangementwhich will obtain the eilects of a lined screen, whether the alternatetransparent and opaque lines or the parall lineator and representingdifferent angular'views of an object, each of said record portionscomprising a plurality of color areas distributed in accordance with thecolor separation of said color screen and representing the naturalcolors of the corresponding portion of said object.

2. A stereoscopic color picture comprising in combination a linedscreen, a color screen associated therewith having colored areasangularly related with respect to the lines of said lined screen, and aphotographic record associated with said lined screen and said colorscreen, said photographic record comprising elementary record portionsaligned with the elements of said lined screen and representingdifferent angular views of an object, each of said record portionscomprising a plurality of color areas distributed in accordance with thecolor separation of said color screen and representing the naturalcolors of the corresponding portion of said object.

3. A stereoscopic color picture comprising in combination a linedscreen, a color screen associated therewith having colored arearsarranged approximately at right-angles to the lines of the lined screen,and a photographic record associated with said lined screen and saidcolor screen, said color screen being arranged between the lined screenand the photographic record, said photographic record comprisingelementary record portions aligned with the elements of said linedscreen and representing different angular views of an object, each ofsaid record portions comprising a plurality of color areas distributedin accordance with the color separation of said color screen andrepresenting the natural colors of the corresponding portion ofsaidobject.

4. In a stereoscopic picture, the combination oi a lineator, a colorscreen associated therewith comprising colored areas angularly relatedto the lines of the lineator, and a positive picture having areasrepresenting diierent angular views of an object and so distributedrelative to the lineator as to produce a stereoscopic effect when viewedthrough the lineator, each of said lastmentioned areas comprising aplurality of color areas so distributed relative to the color screen asto reproduce the natural colors of the corresponding part of the objectphotographed.

5. In a stereoscopic picture, the combination of a lined screen, a colorscreen associated therewith comprising colored lines angularly relatedto the lines of the'lined screen, and a photographic positive havingareas representing different angular views of an object and sodistributed relative to the linedscreen as to produce a stereoscopiceiect when viewed through the lined screen, each of said areascomprising a plurality of color areas so distributed relative to thecolor screen as to reproduce the natural colors of the correspondingpart of the objectphotographed.

6. Inl a stereoscopic picture, the combination of a lined screen, acolor screen associated therewith and having colored lines approximatelyat right anjgles to the lines of the lined screen and a photographicpositive having areas representing different angular views ot an objectand so distributed relative to the lined screen as to produce astereoscopic efiect when viewed through the lined screen, each of saidareas comprising a plurality of color areas so distributed relative tothe color screen as to reproduce the natural colors of the correspondingpart of the object photographed.

7. In a stereoscopic picture, the combination of a lined screen, a-colorscreen associated therewith and having colored linesl approximately Iatright-angles to the lines o! the lined screen, and a photographicpositive having areas representing dierent angular views of an objectand so distributed relative to the lined screen as to produce -astereoscopic effect when viewed through the lined screen, each of saidareas comprising a plurality of color areas so distributed relative tothey color screen as to reproduce the natural colors of thecorresponding part ,of the object photographed, said color screen beingarranged between the lined screen and the photographic positive.
